摘要
为研究船员视觉特征和疲劳驾驶行为间的关系,用访谈调查与实船试验相结合的方法获取相关数据并对其进行分析。运用集对分析(SPA)技术,构建以目标区视点分布比、注视时间比例、瞳孔直径、目视区域距离为自变量集合,舵盘变换幅度为因变量集合的关系模型。对模型进行检验,证实其有效性和可靠性。模型结果表明,船员的4个视觉特征指标对疲劳驾驶行为均有一定的影响,影响存在较大的不确定性,且影响度不同,其中注视时间比例对疲劳驾驶行为的影响度最大。
In order to study the relationship between crews＂ visual characteristics and fatigue piloting behavior, the method of interview survey combined with ship trial was adopted to get relevant data for anal- ysis. A model was built for the relationship, using set pair analysis technology, and taking target zone viewpoint distribution ratio, watching time in percentage of total time, pupil size, the distance of the visual object as the independent variable set, rudder amplitude range as the dependent variable set. The model was tested to confirm its validity and reliability. The model results show that the 4 crews＇visual characteris- tic indexes have a certain impact on the fatigue piloting behavior , the impact has a big uncertainty and the influence degree is different, watching time in percentage of total time has the largest influence degree on fatigue driving politing among them.
